draw a veil over sth

If you draw a veil over a particular subject, you do not speak about it because it is unpleasant and you do not want to think about it.

如果你对某一特定的话题draw a veil，那么就是说你不会谈论它，因为它令人不快，你也不想去想它。

不提及，避讳(某个话题)

Yes, well I think we'll just draw a veil over what went on last night.

是啊，我想昨晚发生的事情我们就不要提了。

Can we please draw a veil over that stupid rumor about me? It's not true, but I want as few people to hear about it as possible.

我们能不能不要提那个关于我的可笑传言了?那并不是真的，但是我还是希望越少人知道越好。
